Definitions

  • the invention relates to a device for the automatic, controllable delivery of a lubricant to a lubrication system according to the preamble of claim 1.
  • a device of the type mentioned is known from German patent 25 20 241 and from US patent 4,023,648.
  • an essentially cylindrical container has a funnel-shaped bottom, which is provided with a screw-on, nipple-shaped lubrication outlet which can be screwed onto a lubrication system, for example onto the lubrication point of a bearing, instead of a standard lubrication cap.
  • An insert is attached to the end of the container, which lies opposite the bottom.
  • a movable separating device separates the container between the bottom and the insert, in a lubricant-tight manner, into a lower lubricant chamber and into an upper compressed gas chamber, the separating device enclosing a gastight, expandable diaphragm and a piston movable along the inner wall of the container which prevents the penetration of lubricant from the lubricant chamber into the upper part of the container by means of sealing rings.

  • the device mentioned at the outset has the features stated in the characterizing part of patent claim 1.
  • the device according to the invention makes it possible to lubricate without any impairment of the piston and the refill essential gas and lubricant-related sealants.
  • the device allows replacement lubricant to be introduced into the lubricant chamber in a simple and clean manner, for which purpose the lubricant can be packaged in a flexible casing, so that any risk of lubricant being carried over into the container is excluded.
  • the pressure-generating galvanic cells can be replaced just as easily and safely as is usual with other electrical and electronic devices.
  • the replacement of the consumables in no way adversely affects the other essential, cost-intensive parts of the device, so that the user of the device actually only the cost of the lubricant used over many years and charge the depleted galvanic cells uss.
  • Another advantage of the device according to the invention is that the out of the pressure gas development and thus the amount of lubricant dispensed per unit of time can be continuously changed by a simple rotary movement of an adjusting element and can also be reset at any time.

However, the known galvanic cell at hand has a different electrical den Material and a different structure than the cells mentioned for hearing aids.
  • such a cell is designed according to German Offenlegungsschrift 35 32 335 for the development of hydrogen gas, which is generated by connecting the electrodes of the cell to an external closing resistance, one electrode permeable to hydrogen and the encapsulation the cell is provided with at least one small opening for the release of the developed hydrogen gas.

  • the present device can be designed in particular as follows:
  • the resistance element can be designed such that it has a strong positive resistance coefficient. Accordingly, the closing resistance of the galvanic double cell 34 increases with increasing temperature, so that less gas is developed and a lower gas pressure is exerted on the piston;
  • plastic materials of the container 1 and the piston 23 can have different thermal expansion coefficients, the expansion coefficient of the material of the piston being greater than that of the container. Accordingly, the friction resistance of the piston increases with increasing temperature, so that the decreasing viscosity of the lubricant is at least partially compensated for.

Abstract

Un récipient cylindrique (1) est pourvu d'un couvercle conique à visser (2) qui comprend un raccord fileté (4) de vissage sur un système de lubrification. Un piston (23) mobile pourvu d'une bague d'étanchéité (28) sépare le récipient (1) en une chambre de lubrifiant (30) et en une chambre de gaz sous pression (29). On peut introduire dans la chambre de lubrifiant (30) du lubrifiant (32) conditionné dans une enveloppe flexible (31), après avoir enlevé le couvercle à visser (2). Le récipient (1) contient un espace (17) en forme de godet, situé au-dessus de la chambre de gaz sous pression (29) et fermable de manière étanche aux gaz par un couvercle à visser (12). Dans cet espace (17), qui est en communication avec la chambre de gaz sous pression (29) par un orifice (18) de passage du gaz, est agencée une double cellule galvanique (34) destinée à la production d'un gaz sous pression qui agit sur le piston (23). La production de gaz provoquée par le flux de courant à travers la cellule galvanique (34) peut être sélectionnée au moyen d'un élément de résistance (48) ajustable logé dans l'espace (17) du récipient (1). Cet appareil permet de compléter ou de remplacer facilement et rapidement à n'importe quel moment les matières consommables, notamment le lubrifiant et la cellule galvanique, et de réutiliser les autres parties de l'appareil.
